Description

Technical Field

[0001] This utility model belongs to the field of cable winding technology, specifically a cable winding device. Background Technology

[0002] In modern mining operations, hydraulic double-arm bolt drilling rigs play a crucial role. Their high efficiency and flexible operation make them key equipment for ensuring the progress and quality of mining operations. However, their associated cable reeling devices face numerous problems that urgently need to be addressed.

[0003] Hydraulic twin-arm anchor drilling rigs frequently move in the complex downhole working environment, resulting in extremely frequent cable winding and unwinding operations. In traditional cable winding processes, the harsh downhole environment becomes particularly problematic when the cable needs to be wound onto the drum. The abundant gravel and sludge found downhole adhere extensively to the cable surface.

[0004] When cables covered in debris are wound onto a reel, friction between the cable and the gravel and mud is unavoidable. This friction continuously wears down the cable's insulation, reducing its insulation performance. From an electrical safety perspective, reduced cable insulation performance means a significant increase in the risk of leakage, which not only damages the equipment itself but also poses a serious threat to the lives of personnel working underground.

[0005] Existing hydraulic double-arm anchor drilling rig cable winding devices are inadequate in addressing these problems. Most winding devices only have basic cable winding functions and lack effective cleaning mechanisms, making it impossible to clean fine gravel and mud from the cable surface before winding. Even when some devices attempt to add cleaning functions, they often fail to achieve the desired cleaning purpose due to unreasonable structural design and poor cleaning effect. Utility Model Content

[0006] To address the problem that existing hydraulic double-arm anchor drilling rig cable winding devices only have basic cable winding functions and lack an effective cleaning mechanism, making it impossible to clean the cable surface of small stones and mud before winding, and causing continuous wear of the cable insulation layer due to friction between the cable and the stones and mud, thus reducing the cable insulation performance, this utility model provides a cable winding device.

[0007] This utility model is achieved through the following technical solution:

[0008] A cable winding device includes two opposing support plates, with a drum rotatably mounted between the two support plates for winding cables. It also includes a U-shaped cleaning frame, with retractable support rods connecting the left and right sides of the cleaning frame to the two support plates. Four U-shaped rotating shafts are rotatably mounted inside the cleaning frame, with adjacent shafts connected by bevel gears. Brushes extending into the cleaning frame are mounted on the rotating shafts. A motor, connected to one of the rotating shafts, is mounted on the cleaning frame.

[0009] A further improvement of this utility model is that the cleaning frame has a square-shaped shell structure, with an opening on the inner side corresponding to the brush, and an opening at the bottom of the cleaning frame.

[0010] A further improvement of this utility model is that the bottom front and rear sides of the cleaning frame are rotatably equipped with support shafts that can support the rolling of the cable.

[0011] A further improvement of this utility model is that the rotating shaft includes a first rotating shaft, a second rotating shaft, a third rotating shaft, and a fourth rotating shaft arranged vertically in sequence; the motor is connected to the first rotating shaft, two first bevel gears are installed at both ends of the first rotating shaft, a fourth bevel gear that meshes with one of the first bevel gears is installed at the end of the fourth rotating shaft near the first rotating shaft, two second bevel gears are installed at both ends of the second rotating shaft, one of the second bevel gears meshing with the other first bevel gear, and a third bevel gear that meshes with the other second bevel gear is installed at the end of the third rotating shaft near the second rotating shaft.

[0012] A further improvement of this utility model is that baffles that can protect the corresponding bevel gears are provided on the left and right sides of the upper part of the bottom frame of the cleaning frame.

[0013] A further improvement of this utility model is that the support rod has a rectangular cross-section, which includes a first section connected and installed with the cleaning frame and a second section connected and installed with the support plate, and the second section is slidably and telescopically connected to the first section.

[0014] A further improvement of this utility model is that the support plate is provided with a moving groove that can guide the vertical sliding of the support rod, and springs are connected to the upper and lower sides of the end of the support rod near the support plate.

[0015] A further improvement of this utility model is that the support rod is connected to the front and rear sides of the end near the support plate, and the moving groove is provided with sliding grooves that fit the sliding shafts on both sides. The spring is installed vertically in the sliding groove and is connected to the upper and lower sides of the sliding shaft.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0017] During use, the cable passes through the middle of the cleaning frame, and the power mechanism drives the drum to rotate. The motor drives four rotating shafts to rotate synchronously. The brushes on the four shafts rotate to achieve a comprehensive and thorough cleaning of fine gravel and sludge from the cable surface. This avoids the problem of continuous wear on the cable insulation layer caused by friction between the cable and gravel and sludge, greatly improving the safety of cable winding and the cable's service life. As the cable reciprocates left and right on the drum, the left and right retractable support rods allow the cleaning frame to move flexibly left and right with the cable (follow-up movement), avoiding the cleaning frame's restriction on the cable's left and right movement, improving the adaptability of the device, and ensuring the reliability of the drum's cable winding.

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0026] like Figure 1-4 As shown, this utility model discloses a cable winding device, including two support plates 2 arranged vertically opposite to each other (left and right). The two support plates 2 are positioned and installed on a hydraulic double-arm anchor drilling rig. A drum 1 capable of winding cables is rotatably installed between the two support plates 2. This cable winding device also includes a U-shaped cleaning frame 3. The left and right sides of the cleaning frame 3 are respectively connected to the two support plates 2 through telescopic support rods 5. Four U-shaped rotating shafts are rotatably installed inside the cleaning frame 3. Adjacent rotating shafts (vertically) are connected by bevel gear transmission. Brushes 7 that can extend into the cleaning frame 3 and clean the surface of the cable are installed on the rotating shafts. A motor 6 is installed on the cleaning frame 3 and is connected to one of the rotating shafts through transmission.

[0027] When this cable winding device is in use, the cable passes through the middle of the cleaning frame 3. The power mechanism drives the drum 1 to rotate, and the motor 6 drives four rotating shafts to rotate synchronously. The brushes 7 on the four rotating shafts rotate to achieve a comprehensive and thorough cleaning of fine gravel and mud on the cable surface. This avoids the problem of continuous wear on the cable insulation layer caused by friction between the cable and gravel and mud, greatly improving the safety of cable winding and the service life of the cable. During the process of the cable reciprocating on the drum 1, the left and right retractable support rods 5 allow the cleaning frame 3 to move flexibly (follow-up) with the cable, avoiding the restriction of the cleaning frame 3 on the left and right movement of the cable, improving the adaptability of the device, and ensuring the reliability of the drum 1 in winding the cable.

[0028] Among them, the winding of the cable on the drum 1 can be controlled manually by reciprocating left and right.

[0029] Among them, such as Figure 4As shown, the rotating shaft includes a first rotating shaft 11, a second rotating shaft 12, a third rotating shaft 13, and a fourth rotating shaft 14 arranged vertically in sequence. The first rotating shaft 11 is horizontally rotatably installed in the bottom frame of the cleaning frame 3, the second rotating shaft 12 is vertically rotatably installed in the right frame of the cleaning frame 3, the third rotating shaft 13 is horizontally rotatably installed in the upper frame of the cleaning frame 3, and the fourth rotating shaft 14 is vertically rotatably installed in the left frame of the cleaning frame 3. The motor 6 is positioned and installed on the cleaning frame 3 and is connected to one end of the first rotating shaft 11 for transmission. Two first bevel gears 15 are installed at both ends of the first rotating shaft 11. A fourth bevel gear 18 that meshes with the first bevel gear 15 on the left side is installed at the end of the fourth rotating shaft 14 near the first rotating shaft 11 (lower end). Two second bevel gears 16 are installed at the upper and lower ends of the second rotating shaft 12, wherein the lower second bevel gear 16 meshes with the first bevel gear 15 on the right side. A third bevel gear 17 that meshes with the upper second bevel gear 16 is installed at the end of the third rotating shaft 13 near the second rotating shaft 12 (right end). The motor 6 is powered by four rotating shafts and meshing bevel gears, which enable the four shafts to rotate synchronously and stably, providing continuous and uniform cleaning power to the brush 7 and avoiding differences in cleaning effect caused by uneven power transmission.

[0030] Furthermore, the first rotating shaft 11 is rotatably connected to the bottom frame of the cleaning frame 3 at both ends via bearing seats, while the second rotating shaft 12 and the fourth rotating shaft 14 are rotatably connected via two upper bearing seats. This effectively prevents debris falling from the roller brush from entering the bearing seats and affecting the normal rotation of the rotating shafts.

[0031] The cleaning frame 3 has a U-shaped shell structure with an opening on its inner side corresponding to the brush 7. This allows the inner side of the brush 7 to extend out and make contact with the cable, avoiding dead corners and ensuring that fine gravel and sludge on the cable surface are thoroughly removed. This effectively improves the cleanliness of the cable before winding, further protecting the cable insulation layer from wear, reducing the risk of leakage, and ensuring the safety of underground operations. The cleaning frame 3 also has an opening at the bottom, allowing gravel and sludge to fall off the brush and avoid accumulation, ensuring continuous and efficient cleaning. This also prevents debris from contacting the cable again and affecting the cleaning effect. Additionally, it facilitates the inspection and maintenance of the internal rotating shaft.

[0032] The cleaning frame 3 has rotatably mounted support shafts 20 on its bottom front and rear sides, which can support the cable's rotation. The support shafts 20 are positioned higher than the bottom frame of the cleaning frame 3. These support shafts effectively support the cable's rotation, ensuring that the lower brush 7 can reach the bottom of the cable while preventing the cable from contacting the bottom frame of the cleaning frame 3, thus avoiding cable wear and ensuring smooth winding. The presence of the brushes 7 on the left, right, and top sides prevents the cable from contacting the cleaning frame 3.

[0033] Furthermore, in order to protect the outer insulation layer of the cable and prevent wear on the cable insulation layer, a rubber protective layer is provided on the outside of the support shaft 20.

[0034] like Figure 4 As shown, baffles 19 are provided on the left and right sides of the upper part of the bottom frame of the cleaning frame 3 to protect the corresponding bevel gears. The baffles 19 have an obtuse-angle bend structure, including a vertically set second bend section and a first bend section that slopes downward from the outside to the inside. This effectively blocks and guides debris such as gravel and mud, allowing them to fall through the opening at the bottom, thus avoiding impact on the bevel gears and bearing seats, preventing wear and jamming of the bevel gears and bearing seats, ensuring normal and stable operation of the equipment, and extending the overall service life.

[0035] like Figure 2-3 As shown, the support rod 5 has a rectangular cross-section, comprising a first section connected to the cleaning frame 3 and a second section connected to the support plate 2. The second section is slidably and telescopically connected to the first section. This ensures the cleaning frame 3 remains vertical while allowing it to move left and right with the cable, thus providing flexibility and practicality for cable winding.

[0036] Furthermore, such as Figure 2 , 3 As shown in Figure 5, the support plate 2 has a movable groove 4 that can vertically guide the end of the support rod 5. Springs 10 are connected to the upper and lower sides of the end of the support rod 5 near the support plate 2 (outer end). The upper and lower sides of the outer end of the support rod 5 are elastically connected (supported or tightened) by the springs 10 on the upper and lower sides. During the cable winding process, the cleaning frame 3 can be slightly adjusted up and down (followed) according to the change of the cable winding diameter, so as to ensure that the inner hole of the cleaning frame 3 is adapted to the diameter of the cable on the drum 1, thus achieving flexibility in use.

[0037] Furthermore, such as Figure 5 As shown, the support rod 5 has sliding shafts 8 connected to both the front and rear sides of its end near the support plate 2. Sliding grooves 9, which engage with (guide the sliding shafts 8), are provided on both sides of the moving groove 4. The spring 10 is vertically installed within the sliding grooves 9 and connected to the upper and lower sides of the sliding shafts 8. A T-shaped structure is formed at the outer end of the support rod 5, which restricts and guides the sliding shafts 8 through the sliding grooves 9, preventing the support rod 5 from detaching from the moving groove 4 and ensuring reliability and stability. Furthermore, the spring 10 is installed within the relatively small cross-section of the sliding groove 9, effectively preventing torsional deformation during its extension and retraction.

[0038] In this cable winding device, the cable passes through the middle of the cleaning frame 3. A power mechanism drives the drum 1 to rotate, and a motor 6 drives four rotating shafts to rotate synchronously. The brushes 7 on these shafts rotate, achieving a comprehensive and thorough cleaning of the cable surface from fine gravel and sludge. This avoids the problem of continuous wear on the cable's insulation layer caused by friction between the cable and the gravel and sludge, greatly improving the safety of cable winding and extending the cable's service life. During the reciprocating winding of the cable on the drum 1, the left and right retractable support rods 5 allow the cleaning frame 3 to move flexibly left and right with the cable (follow-up movement), avoiding any restriction on the cable's left and right movement by the cleaning frame 3, improving the device's adaptability, and ensuring the reliability of the drum 1's cable winding.
